I recently rewatched the episode "Deep Freeze", in which a wealthy theme-park owner kidnaps Mr. Freeze, takes him to his futuristic theme-park/ city of tomorrow, and wants Freeze to build him a cryogenic suit like his to live forever. The episode is 20 years old and I just realized today it's an homage to Walt Disney, Epcot and the frozen head rumors. Man, I love that show.
Daily Sketch: The Riddler
I've always preferred the 3-piece suit Riddler (my favorite Bat-villian), but the unitard is a fun design too.
